How to choose oscilloscope voltage probes for motor drive measurements?
When selecting oscilloscope voltage probes for motor drive measurements, it is important to consider: Motor drive measurements involve relatively high voltages. For example, the DC bus voltage in a 480 Vac three-phase motor drive is typically around 680 Vdc.
How do you use AC coupling in an oscilloscope?
To accurately measure the AC signal, one needs to remove the DC portion. Using AC Coupling When using a passive probe, one may use the oscilloscope's AC coupling feature to block the DC component at the input and show only the AC signal. AC coupling (or "DC Block") works by inserting a capacitor into the oscilloscope's input path.
Why do oscilloscopes use DC offset instead of AC coupling?
Using DC offset is preferable to using AC coupling, since the offset method allows you to see changes in the DC level that may be part of the measured signal. Also by removing the DC voltage component at the beginning of the signal path, the entire dynamic range of the oscilloscope's input is preserved.
What is a 3v3i oscilloscope?
The three-wattmeter configuration requires six oscilloscope channels: 3 voltages and 3 currents. This 3V3I configuration provides individual phase-to-neutral voltages and the power in each individual phase, which is not available in the two-wattmeter configuration.
